Though it might be hard to motivate to head to the steps, here are three reasons to love them:

They provide a natural heart pumping workout. Run up, and then slow it down on the way down. This also gives you a nice break in between sets to recover!

You can do a lot of variations on the stairs, you don't have to run every set. Try doing two or three at a time and adding a lunge in between. Side step up them, switching sides half way through to give your glutes and extra boost. Or try walking up them backwards.
